2. CHECKLIST The system utilizes high-pressure water and air to transform hydrogen sulfide into water and elemental sulfur. This solid collects on the bottom of the tank to be periodically purged. This process requires a minimum contact time of 55 minutes (on 68 F water) per PPM sulfide to complete. The system will provide on demand or all at once, sulfur free water equal to 38% of the water storage capacity and 75% of the storage capacity of the contact tank. Using the chart below, ensure the system you select is properly sized for the job, with the additional contact tanks if required. This sizing chart is for average households with typical water use patterns. Large hot tubs or other high volume fixtures should be added to the typical contact volume required. For example, a 2-person home with 2-ppm sulfide and an 80-gallon whirlpool tub would require an additional 80 or 120-gallon contact tank. Use the OX120B5 or OX120U5 for 5-9 GPM applications, the OX120B10 or OX120U10 for 10-15 GPM applications. Use the OX120U5I for 5-9 GPM treated and 30 GPM raw applications by adding the bypass check as shown in 4.A.3. Use the Oxidizer 80 or 120 gallon well tank with 15 GPM Inductor and optional 1-1/2 hp pressure booster for 15-25 GPM treated applications instead of the models in this manual. The well pump must be able to supply the minimum gallons per minute to the system at a pressure of at least 80 PSI to not use a booster pump.

4.A PLUMBING THE SYSTEM (without a pressure booster) In order for the well pump to be eligible to drive the oxidation process through the Inductor on the standard system, the well pump must be able to supply a minimum of 5 gallons per minute to the system at a pressure of at least 80 PSI. If the pump is not capable of maintaining that pressure then use the booster pump which will also provide better pressure to the home. Sulfur concentrations over 10-ppm sulfide must have a minimum 90 PSI. Pressure on the well line from the well pump to the Inductor inlet may exceed 80 PSI. If you are using your own pressure booster, follow the directions under section 4.B PLUMBING THE SYSTEM WITH BOOSTER PUMP on page 7 substituting your own pump and pressure switch. Make certain that the pump performance curve is adequate before selecting any other pressure-boosting pump. If you need raw water for irrigation from the same well and are using the well pump without a booster pump, use the Raw Water Bypass option for 1-PPM sulfide. Use a different model, the Odor Oxidizer Pressure Tank with Raw Water Bypass option for 1-10 PPM sulfide or add a pressure booster to this model. Locate near drain adequate for the pressure relief or the momentary purge of sulfur compounds, which are trapped in the sump. The system should be installed in a dry location that provides adequate space for installation and service. As components age leaks may occur, therefore, do not locate in an area where water from the tank can cause property damage. Do not treat water over 100 F. Do not expose the system to temperatures below freezing as water freezing in the tank or components will break them. 5

4.A PLUMBING THE SYSTEM (without a pressure booster)(continued) 1 Position the Oxidation Tank as close to the well pump discharge as is practical using the Tank as the pressure tank for controlling the well pump. Also locate near the existing pressure switch so the control line can be as short as possible. See the installation diagram previous page. 2 Assemble the Air Inductor assembly as shown. Orient the pressure gauges so they can be read, but hand tight only. Inlet pressure gauge seals against an O-ring, however the system pressure gauge requires Teflon tape to seal. Install the Air Filter finger tight only as it may be removed later. Secure all unions hand tight. 3 Glue the outlet port of the Air Inductor to the Tank inlet. Note: If you are using the raw water bypass option, plumb a tee at the tank inlet and branch to the optional union check with the arrow towards the well pump. 4 Plumb the inlet of the Air Inductor to the well pump discharge line. Note: If you are using the raw water bypass option, Tee the check outlet to the well line at the Inductor inlet as shown. Do not reduce or restrict the well line. 5 Install a drain valve on the Tank drain and plumb the drain to the exterior or use a hose. Plumb the pressure relief to the exterior. Plumb the relief valve to a suitable drain. Failure to do so can result in flooding and property damage. 6 Remove the existing well pump Square D FSG pressure switch (if installed) and install the new pressure switch spring provided in the kit. This will give the desired pressure differential when adjusted later. Thread the ¼ Ell provided into the port on the pressure switch with Teflon tape finger tight. Loosen the compression nut then press one end of the ¼ tubing provided into the fitting so that the tubing is past the seal, then secure the nut finger tight. Plug the vacated switch connection. 7 Wire the pressure switch per local code. Secure the switch to the plumbing at a convenient location using the two switch clamps provided. The clamps attach to the switch from the bottom through the ground lug taps. Secure the ground to the new lugs the clamps provide. 8 Press the other end of the pressure control line from the pressure switch onto the control line fitting on top of the Air Inductor outlet. 9 Connect the vent line at the base to 3/8 polyethylene tubing (not provided) and run the length of tubing to the exterior. Air released from this line is humid and may corrode metal in the vicinity. Should the vent valve malfunction, water can spray from the line. Plumb the vent line to the exterior or to a suitable drain. 10 Plumb the outlet of the Tank with a ball valve to the treated line or contact tank inlet, if additional contact is needed. 11 When using a contact tank, install a drain valve on the Tank drain to the exterior as done in step 5, and then plumb the contact tank outlet to the treated line as done in step 10, or the next contact tank if additional contact is required. 6

4.B PLUMBING THE PRESSURE BOOSTED SYSTEM Locate near drain adequate for: The pressure relief and to drain the vessel. This system should be installed in a dry location that provides adequate space for installation and service. As components age leaks may occur, do not locate in an area where water from the tank can cause property damage. If installed outdoors in temperate regions, avoid roof drip edges that can concentrate rain fall onto the pump motor, or areas that flood and may submerge the motor. Any water treatment or handling equipment installed upstream must be vacuum resistant or vacuum protected in the event of a supply failure. Water pressure from the well must be from 10-50 PSI. The flow rate must always be greater than 5 GPM. An interruption of the water supply can result in heat damage and potential failure and leaking at the booster pump. To reduce this risk, your product includes a temperature-sensing switch that is designed to turn off if the pump is over-heated. Do not alter or remove this sensor. Electrocution and explosion hazard! Before working on this product, turn off the power to the pump and release the pressure in the system. Never install two pumps that draw in parallel on the same suction line or artesian well line. One pump will cause the other to become vapor locked and not perform properly or over-heat. Do not allow partially cured glue or other plumbing debris to enter the booster pump or Inductor at start-up. Always flush lines. Do not over-tighten fittings. Plastic treaded fittings should be snug; unions should be hand tight only. Make certain the pump performance curve is adequate before selecting any other pressure-boosting pump. Wire the pressure booster to the pressure switch as indicated by the pump manufacturer in compliance with local codes. To make wiring the booster pump easier, prior to the installation determine the best available electrical source. Then following the instructions 5. Wiring the Pressure Booster: connect with the ½ nut and wire the pressure switch to the booster. Then select the proper voltage wiring per the diagram on the pump motor and replace the motor connection access plate. This is much easier to do on a bench than on the floor. 7

4.B PLUMBING THE PRESSURE BOOSTED SYSTEM (CONTINUED) 1 Position the Oxidizer Tank and Booster Pump as shown previous page. The system must be plumbed in after the well pump pressure tank and any raw waterline must tee into the line ahead of the Pump inlet. 2 Assemble the Air Inductor assembly as shown. Orient the pressure gauges so they can be read, but hand tight only. Inlet pressure gauge seals against an O-ring, however the system pressure gauge requires Teflon tape to seal. Install the Air Filter finger tight only as it may be removed later in the installation. Secure all union connections hand tight. 3 Glue the outlet port of the Air Inductor to the inlet of the Tank. If you are feeding solution with a chemical pump, plumb a tee in the line between the Air Inductor and the Tank inlet for the injector. Avoid feeding chemicals ahead of the Air Inductor, as it may lead to scaling and sacrifice the performance of the air Induction. 4 Make a pump discharge fitting as shown with a 1 union. Thread the fitting into the end or discharge of the Booster Pump as shown. 8

4.B PLUMBING THE PRESSURE BOOSTED SYSTEM (CONTINUED) 5 Glue the Air Inductor inlet fitting to the Booster Pump discharge fitting using 1 NPS pipe. If you wish to elevate the Booster or locate the Pump on the inlet side, then you can glue 1 NPS ell(s) to the discharge pipe and set the pump horizontally even at another location within 20 using as few ell as is practical. The control line provided is only 6 long. 6 Plumb the supply line from the well tank to the inlet (top) of the Booster with a union. Make certain that all raw waterlines tee from the supply before the Booster inlet. Set the well pump cutout pressure so that it is lower than the Booster cut-in pressure (55-75 PSI). 7 Install a drain valve on the Tank drain and plumb the drain line to the exterior or adequate drain. Plumb the pressure relief discharge to the exterior or an adequate drain. Plumb the relief valve discharge to the exterior or a suitable drain. Failure to do so can result in flooding and property damage. 8 Thread the ¼ Ell provided into the port on the pressure switch with Teflon tape finger tight. Loosen the compression nut then press one end of the ¼ tubing provided into the fitting so that the tubing is past the seal, then secure the nut finger tight. 9 Press the other end of the pressure control line onto the pressure control fitting on top of the Air Inductor outlet. 10 Connect to the vent line 3/8 polyethylene tubing (not provided) and run the length of tubing to the exterior. The air released from this line is humid and may corrode metal in the vicinity. Should the vent valve malfunction water can spray from the line. 11 Plumb the outlet of the Tank with a ball valve to the treated line or contact tank, if required. 12 When using a contact tank, install a drain valve on the Tank drain as done above in step 7 and plumb to the exterior or an adequate drain. Plumb the tank outlet as done in step 11 to the treated line or contact tank if additional contact is required. 9

5. WIRING THE PRESSURE BOOSTER All wiring and fuse sizing are preliminary recommendations only. For your safety, local codes and in their absence, national codes must be followed to minimize risk of electrical shock, property damage or personal injury. Grounding the pump is essential for your protection and the protection of the motor. All wiring should be completed by a trained electrician and or qualified professional. The voltage of the pump must match the voltage of the power source. The ½ hp booster pump is factory set for 115 Volts. To connect to 230 volts make certain the power source is disconnected then wire to the junction box. Change the motor voltage setting on the booster motor following the wiring diagram located below and on the motor label. The ¾ & larger hp booster pumps are factory preset for 230 volts. The power leads should be large enough to carry the rated amperage. 1 Remove the plastic cover from the pressure switch and the lock nut from the ½ connector to the motor. Place the switch on the connector secured to the motor and secure the switch horizontally with the lock nut. Remove the electrical access plate from the back of the motor. 2 Pass the two pressure switch wires through the connector as shown. 3 Attach one of the pressure switch wire leads to the Line # 1 push-on tab and then attach the other lead to the Line # 4 push-on tab on the motor terminal board. If changing the voltage move the other wires as indicated in the diagram below. Replace the motor access plate when wiring is complete. 4 Now wire the pressure switch placing the ground on the ground lug first then placing the lines or the line and common on the two outside lugs. Connect the wiring at the electrical source. Replace the cover when wiring is complete. Secure the wires with the lug nuts firmly as loose lugs cause arcing and subsequent heat damage and failure. 10

6. STARTUP & ADJUSTMENT 1 After completing the plumbing remove the inlet union nut to the Air Inductor or to the booster pump and separate the line so the line can be flushed out to a bucket or drain. Turn the well pump on momentarily to flush out any line debris. Then reconnect the union. Line debris can cause the Air Inductor or the booster pump to malfunction, always flush the lines prior to pressurizing. 2 Turn off any drain valves and the Oxidizer Tank outlet valve. Restore power to the well pump and pressurize the system. You will hear water rush through into the Tank and later hear air venting from the vent valve until water reaches the set level. If using a booster pump: Immediately turn on power to the pressure booster. After the system is pressurized check for leaks. Often some vibration will occur in the Air Inductor. This will diminish in an hour and completely disappear in days as air from the installation trapped in the bypass damper is adsorbed. 3 Adjust the pressure switch to the desired pressure 59-74 PSI. It may be necessary to cycle the pump several times to achieve the proper setting. While filling the Tank and at cut-in the inlet pressure will be around 40 PSI greater. If not using a booster pump: The inlet pressure on the Air Inductor must be 20 PSI greater than the cut-out pressure setting on the Oxidizer Tank. The Air Inductor must draw air through the entire pump cycle. Air induction must be constant for thorough treatment. Check at this time that air is drawn when the system pump runs. Run the Oxidation Tank pressure as high as possible while still inducting air gives a longer pump cycle and higher oxygen levels for treatment. Never exceed the working pressure rating on the Tank. Higher pressure than rated can damage the unit; void the warrantee and cause flooding damage. 4 If using a contact tank to extend treatment capacity, fill the contact tank with the outlet valve off. Throttle the Oxidizer Tank outlet valve so pressure remains constant while filling the contact tank. Once pressurized open valve and vent the air displaced from the contact tank so it doesn t enter the home. Sulfur will be gone in the number of hours equal to the concentration of sulfide in PPM. (Example: 10 ppm H2S take 10 hours to remove). Waterlines require several day to clear up. Extremely caked lines require several weeks and line flushing to clear up completely. 11
